Background

In the field of affective neuroscience and beyond, facial expressions—and, more recently, body postures—have received considerable attention, becoming preferred stimuli for the study of emotions. Investigating how emotions are conveyed and recognized through both facial expressions and bodily postures has important implications for achieving a more ecologically valid understanding of human behavior, as both types of cues are essential for accurately perceiving others’ emotions and intentions.

This Research Topic will explore the methodological and ethical challenges involved in conducting studies of this kind, seeking to critically evaluate and enhance current methodologies that investigate emotions through bodily and facial cues. Among these, we consider not only the more traditional and widespread methods such as the Facial Action Coding System (FACS), emotion recognition software (e.g., FaceReader), techniques for recording physiological parameters (e.g., heart rate variability, skin conductance response), neuroimaging techniques (e.g., functional magnetic resonance imaging [fMRI]) and electroencephalography, but also the more recent facial recognition systems developed with AI and/or neural networks and deep learning.

The aim is to foster advancements toward authentic ecological settings that mirror real-time human interactions more closely and realistically. The emphasis is on overcoming the predominant reliance on staged, unrepresentative samples(of both participants and stimuli) that do not accurately reflect the diversity and complexity of real human emotions.

By addressing these methodological challenges, such as limited ecological validity and the lack of real-world context, the collection aims to develop innovative, realistic stimuli and methods, such as immersive environments and naturalistic interactions, that ensure broader applicability and deeper insight into human emotional dynamics.

Central areas to this theme include, but are not limited to, the following:

Emotional Recognition Mechanisms and the Exploration of Cognitive and Neural Processes Behind Emotion Detection: This theme welcomes contributions that investigate the underlying cognitive and neural mechanisms involved in recognizing emotions, particularly through bodily postures and facial expressions. Topics of interest include, but are not limited to, the role of perception, attention, memory, and individual differences in the accuracy and interpretation of emotional cues. Papers may also examine the influence of cultural, social, or environmental factors on emotion recognition, as well as the implications for improving emotion-based technologies or interventions.

Current Methodological Challenges: Research that highlights the necessity for ecologically valid stimuli that encapsulate the complexity of real-life emotions. This welcomes discussions on developing more naturalistic stimuli and experimental paradigms that reflect genuine social contexts.

Bias Awareness and Mitigation: Investigating the impact of inherent biases—stemming from race, gender, ethnicity and neurodiversity—in research settings. Contributors are encouraged to examine how these biases affect stimuli selection, experimental design, and the generalizability of results. Strategies, such as diversifying participant samples, implementing blind or double-blind study designs, and utilizing algorithmic fairness tools, to mitigate these biases in future research are also welcomed.

Interdisciplinary Perspectives: Studies that emphasize the importance of cross-disciplinary integration, giving insights in philosophical, psychological, and neuroscientific perspectives to broaden our understanding of emotional expression and recognition.

This Research Topic welcomes discussions and innovations that promote inclusivity and realism in emotion science, addressing key biases and methodological constraints. We encourage submissions that are at the forefront of exploring these dynamic interactions, aiming to bridge gaps and integrate varied academic insights for a richer, more inclusive approach to emotion research.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
